Postman API integration with JIRA cloud

[Manthan]

I am trying to integrate Postman API with JIRA cloud, please can anyone advise how would I achieve this?

I am not sure what you mean by "Postman API". 

Postman usually refers to a tool that you can use to make REST calls to systems, not something that has an API itself.  Jira Cloud has a REST API, and to get started with that, have a look at https://developer.atlassian.com/cloud/jira/platform/rest/v3
